The Composite Performance Index (CPI) is a number from 1-100 that represents the extent to which students have attained or are progressing toward proficiency in a given subject. Students who demonstrate proficiency on MCAS tests, and students with severe cognitive disabilities who score at the Progressing level on the MCAS-Alternate assessment, receive 100 CPI points. Our district's CPIs for 2018 are below.
